Google App Scripts curl authorization

Question

Just trying to play with google app scripts. In anonymous mode things seem fine. Except that anyone can call my script simply like that snippet shows:

curl "https://script.google.com/macros/s/.../exec?ip=\"$myIp\""

I used this manual for tips on how to authenticate through GoogleLogin. The problem is "401 Unauthorized" I received when sent auth token and "Me(owner)/Only myself" options were set on google side. (The token seems correct itself. If I omit password or mistype it, then I receive "Bad auth") If I set "Anyone, even anonymous" again, it works, but auth stuff seems like ignored. What's the correct way to do the trick?

#!/bin/bash
gmail=$1
password=$2
myIp=$3
GoogleAuthToken=""
GoogleAuthToken=`curl --silent https://www.google.com/accounts/ClientLogin --data-urlencode Email=$gmail \
--data-urlencode Passwd=$password -d accountType=GOOGLE -d source=YouDontSay -d service=lh2`
echo $GoogleAuthToken
GoogleAuthToken=$(echo "$GoogleAuthToken" | grep 'Auth=' | sed  s/Auth=//)
echo $GoogleAuthToken 
curl -L --silent --header "Authorization: GoogleLogin auth=$GoogleAuthToken" "https://script.google.com/macros/s/.../exec?ip=\"$myIp\""

Answer 1

You use ClientLogin

https://www.google.com/accounts/ClientLogin

This is google error :

Important: ClientLogin has been officially deprecated since April 20, 2012 and is now no longer available. Requests to ClientLogin will fail with a HTTP 404 response. We encourage you to migrate to OAuth 2.0 as soon as possible.
